Compatible third party lenses for R7

[lovetoshoot2023]

I’m coming from the Sony A mount world where I primarily used 2 Tamron products: an 18-270 and a 150-600mm lens. After purchasing my R7 I have become disappointed by the lack of compatible third party products. What lenses would you suggest that would be like the ones I used with my Sony camera?

Absolutely agree Bill, but that was not my issue.  The response from Canon Japan was.

Trevor,

Well said.  I hope Denny can realize the tremendous value and potential he has with the R7.  Also the importance of investing in Canon's "shooting system" which I believe to be the best available.  Yes, I am a fan of Canon products.  They earned this respect and brand loyalty by providing a level of quality unmatched by other brands.

Thank Rick.   I have been a Canon user for about 43 years now, even though I shoot with other brands, their equipment by far makes up the majority of my gear.   While I believe there are no bad brands among the major OEMs, I believe Canon have the lead in the market place for a good reason.   That is not to say they are not without fault and I point the finger more at their marketing department than anywhere else, over-emphasizing specific features that may not be able to deliver on the hype; while their branding team had what (down under) we would describe as a 'brain-fart' by mis-labelling the R7 and creating unreasonable expectations.  IMHO, the R7 is a capable camera under most circumstances and is providing good service to many, many users.  It's a reasonable update from the EOS 90D, it's just not at the 7D series level.

Trevor,

Thanks for your insights and examples. 
You are certainly getting some great results with the Sigma lens.

Could you explain further Canon’s rationale for developing the RF mount?

In answer to your previous post the final result for me is typically a printed 8x10 calendar distributed to family. For my non-commercial purpose the Tamron lenses worked fine. I was lured to Canon’s R7 by the autofocus system for the money.

Check out Canon's History of Lens Mounts which includes a short video on the new RF mount.

Thanks.

The video was informative.

Thanks for your informative response!  As I see you have been well served by Ricky's video reference on the thinking behind the RF mount.

For your situation, from the point of producing an 8x10 calendar, almost any reputable brand will work for your purposes.  That said, I would honestly considering the following combination of lenses:
RF-S 18-150 IS USM lens.   A great walk-around unit that has a fast and silent ultra-sonic focusing system, Image stabilization that will work with that of the camera (a good reason for going with the Canon brand) and is very light and extremely compact, making it a very convenient lens to leave on your R7.  There is a reason Canon created this unit as a kit lens for the R7 and R10 bodies.   See Canon RF-s 18-150mm IS STM Review & Sample Images by Ken Rockwell

I can personally recommend the Sigma 150-600 Contemporary lens for EF mount. I have not owned Tamron's later version but my respected colleague Ernie (Ebiggs1) has positive things to say about it.  For a review of the lens and comparison of the two you might want to watch: 
(21) Sigma 150-600 f/5-6.3 OS Contemporary Super Telephoto Review - YouTube

Use it via the adapter (which works flawlessly) for your wildlife activities and you essentially have the range from 18mm to 600mm covered.  If you really want to stick with a 3rd party lens you can do so by getting one with an EF mount and using the Canon EF-RF adapter.

Trevor,

Thanks for sharing your thoughts on this topic. Real world experiences can be great lessons.

[Tronhard]

You're most welcome.  I hope you find a combination that works for you and gives you results that are satisfactory.

You are talking absolute rubbish about Duade. He mentioned that inconvenience of switching IS off while mounting on tripod. The issue with this sigma lens is absolute real especially when subject is closed to MFD.
